Abstract

In order to understand the combustion condition of the opposed jetting combustor in different flow conditions, a non-premixed combustor with opposed methane jets was studied in this paper by using the commercial fluid dynamic software based in N-S equation. It was found that, in the non-premixed combustor, when the velocity of methane remain unchanged, the flame moved to downstream with the air velocity increasing; the temperature difference between the steel wall and quartz wall is positively correlated to the air velocity. Under the medium or huge methane velocity, the methane efficiency gets higher with the increase of air velocity.
